To ill-whom# may concern: Ble-.it ,"'nown that I, DWIGHT 1)..K1NG, a citizen 'of the United States, residingv at of Pennsylvania, have invented certain new vand usetul Improvements in Lamps, ci

Whichthe following is a specification.

invention relates to improvements in lamps, and more particularly to an improved lamp designed for use as a tail light on automobiles and other vehicles, the object. of the invention being to provide a lamp divided into two entirely independent compartmentsan-d in one compartment provide a light to perform the double function ot illuminating the license tag and showing a red signal and in the other compartment provide a light designed to. illuminate the road way at the rear of the car whenever desired.

It frequently happens vthat it is desirable to illuminate the. road or street at the rear v of the car.-1T`l1is is particularly true where it is customary to back the car into the garage or to back the car anywhere along the road in turning or in otherwise manipulating the car. This is a source of considerable trouble to driversfend it is the purpose of my invention to provide'a lamp which per- 'forms all the functions of the ordinary tail lamp and 'in addition provides a lamp which operates as a search light to illuminate the road at the rear ofthe car whenever desired.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and ar-A rangements of parts as will be more fully hereinafter described and pointed out in *he claims. l

In the accompanying drawings: 1Figure l a a View elevation illustrating my improvements. Fig. 2 is a view in horizontal se tion on the line 2 2 of Fig. l. Fig. 3 is a `/iew in vertical section on the line 3-3 of Fig. 2, and Fig. Il iso. view in transverse section on the line L-Li of Fig. 2.'

1 represents the casing of my improved lamp which at one side lis provided with an extension 2, and at the inner end of the extension- 2, I provide av removable partition block 3 which divides the casing into a relatively large chamber 4 and a relatively small chamber 5, the latter chamber formed in the extension 2. The end of extension 2 is preferably at an angle as shown at 6, and is provided With a lens 7 through which the light is thrown upon the license tag 8, and while Specification. or Letters Patent.

'my invention is not limited to any `particular support for the license tag, I have shown the same @cured to abracket arm 9 forming an integral part of a bracket 10 secured to the rear Walloi" casing l and adapted to receive a fixed support ll secured to the rearl of the vehicle in any approved manner.`

The block 3 is ci general rectangular shape fitting within the chamber 5, and hase iange lbearing against the wall of chamber 4. This iiange 13 has slots le for the reception of turn buttons l5 to securely lock the block iny place. A socket 16 is provided on one side of block 3 for the reception of an electric lamp 17 and this lamp throws the light through the lens 7 onto the license tag and also illuminates a red lens 18 in the'side of extension 2. The electric wires 19, supplying current to lamp i7, are connected in cir` cuit with the ordinary lighting system of the vehicle so that the ,lamp at night remains illuminated. at all times. A knob' 2() is provided on the block 3 to facilitate its manipulation, and this block 'may be removed to sov alleny access to the interior of chamber 5 whenever desired.

To the rear wall of the relatively large chamber 4;, Isecure a plate 2l. The means illustrated for attaching this plate consist of threaded lugs 22 on the plate projected through' the rear wall of the casing and se cured by'nuts 23, although of course I am not limited tothis particular securin means. This 'plate 2l supports a lamp soclgret 24 in which an electric lamp 25 is located, and a reflector 26 is secured around the socket 24s. The wires 32 supplying electric current to the lamp 25 are connected in a circuit independent ot' the ordinary lighting system of the vehicle, so that the lamp only illuminated at such times as i'f is desired to throw' light on the road at the rear of the vehicle, but ordinarily this lamp is outs The rear wall of the relatively large chamber l of casing l is normally closed by a door 27 having A a hinge 28 atene edge, and a i'as'tening device 29 at its other edge. in this door 27, a 'relatively large lens 30 1s located o as to throw the light in a relatively wide pith.

There will be, of course, sufficient slack in the electric wires to allow these parts to be removed from the casing, and when they are replaced, the chambers 4 and 5 will be entirely separated from each other, and to make this separation proof against light, I

' have provided a gasket 31 between the flange 1 an extension at one side, of a removable block secured to the casmg at the inner end of the'extension, dividing the casing into two chambers, one com rising the main portion vof the casing and t e other the eX- tension,-both of said chambers having lights therein, said extension having a lens at one end for throwing light upon a license tag and having a red lens in one side, and said main port1on in the casing having a lens in its end, substantially as described.

2. A lamp of the character described, compr'ising a casing having an extension at one side, a block removably secured in the casing at the inner end of the extension and dividing the casing into a relatively small havin@` a trans arent port1on. and a D I l located in the relatively large chamber, sdb- 'stantiallv as described.

3. A lamp of the character described, comprisingr a casing havin an extension at one side, a block removaby secured in the casing at the inner end of the extension and dividing the casing into a relatively small chamber in the extension and a relatively large chamber in the main portion of the casing, a lamp socket on the block inside the chamber of the extension, said extension having two transparent portions, one adapted to permit the light to be thrown uponlthe license tag and the other red in color, a door closing the relatively large chamber and having a transparent portion, a pla-te secured in the relatively large chamber and having a lamp socket therein, and a reflector secured around the socket, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
